SPECIFICATION formingpart of Letters Patent No. 687,504, dated November26, 1901.

Original application filed February 6, 1899, Serial No. 104,670.Dividedand this application filed December 8, 1899. Serial 7 No.739,612. (No model.)

T0 all whom it nary concern:

Be it known that I, FRANCIS M. Burns, a citizen of the United States,residing at Ithaca, in the county of Tompkins and State ofNew York, haveinvented certain new and useful Improvements in Governors; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates generally to improvements in governors orspeed-regulators, and particularly to improvements in governors of thetype known as fly-wheel or automatic cut-off governors, though thegovernor herein described may be adapted for the regulation ofthrottle-valves or the tripping-gear of a Corliss engine or any otherdevices for the operation of which governors are employed.

My invention consists in the novel combination and arrangement ofmovable weights by which a governor-weight structureutilizing in itsoperation b'oth centrifugal force and inertia and balanced as to gravitywith respect to its supports is produced.

This application is a division of my application for Letters Patent forimprovements in governors filed February 6, 1899, Serial No. 704,670.

The objects of my invention are to improve and simplify governors, toutilize efiiciently both centrifugal force, so called, and the inertiaof the governor-weights, and to make the governor qnick-actin g,sensitive, reliable, not liable to derangement, and comparativelyinexpensive. These objects are attained in the governor hereindescribed,and illustrated in the drawings which accompany and form apart of this specification, in which the same reference-numeralsindicate the same or corresponding parts, and in which Figure 1 is anelevation of the governor mounted upon a revoluble fiy-wheel, and Fig. 2is a central transverse section thereof.

In the drawings, 1 is the fly-wheel or carrier, and 2 is a weight whichfor convenience may be termed the primary weight. This weight 2 consistsof an arm 2, having at its ends weight masses 2 and 2". It is pivoted tothe fiy-wheel by a pivot-pin 3 and is provided with an extended arm 2 towhich another weight 4, which may be termed the secondaryweight-,ispivoted. Thisweight 4, besides being pivoted to the arm 2",-has pivoted to it an arm 5, which is also pivoted to the fiy-wheel orcarrier 1 at a point 6 and is substantially parallel to the arm 2 of theweight 2. The secondary weight4is so placed that it balances withrespect to the pivot-pin 3 the otherwise-unbalanced gravity of theWeight 2. The entire governor-weight structure is counterbalanced forrotation by a weight mass 7, formed on the ['ly-wheel 1.

The secondary weight 4 is provided with an extended arm 4, terminatingnear the center of the fly-Wheel, which carries an eccentricpin 8, bywhich the valve of the engine may be operated; but I do not limit myselfto mounting the eccentric upon the secondary weight.

The operation of this governor is as follows: When the fly-wheel 1revolves, the action of the centrifugal force tends to move the centerofgravity of the weight 2 upward. Such movement of the weight 2 movesthe weight 4 in the opposite direction, thus carrying the eccentric-pin8 toward the center of the shaft. Because of the peculiar connection ofthe weight 4 to the fly-wheel and weight 2 the motion of the eccentricis in nearly a straight line, its motion being that of an objectcontrolled by two parallel links, which are nearly at right angles tothe direction of the motion. The weight 4 is practically unaffected bycentrifugal force, but does not interfere with the movement of theweight 2 under the infinence of centrifugal force. The weight 4 has apowerful inertia action, however, during times when the speed of theengine is changing, for at such times the inertia tends to move it in adirection substantially at right angles to the link 5 and arm 2". Theinertia action ofthe weight 4 reinforces the combined centrifugal andinertia action of the weight 2, tending to move the eccentric outwardwhen the speed of the engine drops suddenly and to move the eccentricinward when the speed of the engine increases suddenly.

Having thus completely described my invention, what I claim, and desireto secure by Letters Patent, is-

1. In a governor, the combination, with a revoluble fiy-wheel orcarrier, of two-weights, one pivoted eccentrically to the carrier, andhaving weight masses disposed on opposite sides of its pivotal point,the other weight directly connected to the first at a point to one sideof a line connecting said weight masses and intermediate between saidmasses, a link connecting said second weight to the carrier, means forresisting the centrifugal force of the weight structure, and anactuating device adjusted by the movements of the weights.

2. In a governor, the combination, with a revoluble fly-wheel orcarrier, of two weights, one pivoted eccentrically to the carrier, andhaving weight masses disposed on opposite sides of its pivotal point,the other weight directly connected to alateral projection of said firstWeight located at a point intermediate of the weight masses thereof, alink connecting said second weight to thecarrier and arrangedapproximately parallel to the said lateral pro jection, means forresisting centrifugal action of the weight structure, and an actuatingdevice adjusted by the movement of the weights.

3. In a governor, the combination, with a revoluble fly-wheel orcarrier, of two weights, one, an arm, pivoted eccentrically to the carrie'r, the second weight being pivotally connected to the first weightat a point the radius of which is substantially at right angles with thearm, a link forming a second connection of said second weight with thecarrier and arranged approximately parallel to the said radius, meansfor resisting centrifugal action of the weight-structure, and anactuating device adjusted by the movement of the weights;

4. In a governor, the combination, with a revoluble fiy-wheel orcarrier, of two Weights, one, an arm, pivoted eccentrically to thecarrier, the second weight being pivotally connected to the first at apoint theradius of which is substantially at right angles with the arm,a link forming a second connection of said weight with the carrier andarranged approximately parallel to the radius, means for resistingcentrifugal action of the weight structure, and an actuating devicecarried by the second weight and adjusted by the movement of theweights.

5. In a governor, the combination, with a revoluble fly-wheel orcarrier, of two weights, one pivoted eccentrically to the carrier, theother connected to the first weight and having its motion controlled bytwo pivoted and approximately parallel members, both pivotally connectedto the carrier and the said second weight, means for resisting,centrifugal action of the weight structure, and an actuatin g devicecarried by the said second weight, and adjusted by the movement thereof.

In testimony whereof I affix my signature in the'presence of twowitnesses.
